Self-Cleaning Surfaces: Nature's Inspiration

This lecture explores the concept of self-cleaning surfaces inspired by nature, focusing on the properties of superhydrophobicity and photocatalysis. It delves into the mechanisms behind self-cleaning surfaces, such as the role of contact angles and surface roughness. Additionally, it discusses innovative approaches like SLIPS-based self-cleaning and the use of titanium dioxide for photocatalytic self-cleaning. The lecture also covers the development of sustainable living materials, including biodegradable bio-plastics and bio-cements, highlighting their significance in mitigating plastic pollution. The instructor presents research on programmable microbial foundries for sustainable living materials technology, emphasizing the potential of bio-inspired materials in creating environmentally friendly solutions.
